And sorry but if you think a 350 with 305 heads and a 383 lift cam which I didnt even know they made them that small makes unbelievable power then you dont know what real power is you would be lucky to make 200hp now the 400 is heavy and prob is costing him a few hp to rear wheels but motors not going make any more power no matter what gear or trans he has gear and trans just puts power to the road

Hey Pugsy.What up??.

I knew what he meant too.

We had a guy with a 350 Vortec Goodwrench crate in a 4,000 Astro van(yepper that's there wt stock) use that "383" cam with a mod'ed TBI and chip burn.Now not everything has to be over 500 in a lift to be a decent cruiser.Surprising mid curve and very good,no great,street manners.For some that would be a worth while venture.Because of the way the thing pulled in the mid section on a 4,000 van,I would think it is all of 300hp.

Yea that engine you speak of had vortec heads which are way better than the 305 heads on his motor plus other upgrades and you say a 383 cam he said a 383 lift cam doubt you mean same cam and hes talking bout high compression with the 305 heads and then says it runs on 87 one of them statements are wrong high compression and 87 octane gas dont go together and no everything does not have be 500 lift I dont run that small a lift im in 600 lift range but with that said I was just tring clear up a 350 with stock 305 heads and small cam does not make unbelievable power if he wants make that kind of power just find any 350 in a junkyard for few hundred bucks I thought whole deal was a budget 400 hp engine not something my grandma has in her car

"383 lift" could mean lobe lift. I just love it when statements are made so clearly. No decimal points, no nothin'.

As far as "everybody I know says they (L31 Vortec heads) will support 480 lift stock"- do NOT count on it. There have been cases where they will allow 0.480" lift, but that's going to be w/o much if any leeway between the retainer and seal at max lift. There are easy and not so easy ways around this, but in stock form this is a total crap shoot. More on L31 Vortec heads here.

Yea thats why I say I dont know for sure I have no personal knowledge. Of vortec heads as I dont and havent ever used them I was just going by what people say me im a big fan of afr since my first set not going back now plus with the solid roller cams I like to run it would cost me to much to get a set of vortec where they would need to be
